What could make Serena van der Woodsen (Blake Lively), our favorite bad-girl-gone-good, look so blue? Apparently, her life and reputation are on the line!

Yes, you’re looking at brand new “Gossip Girl” wedding scene stills, shot on location today in New York (where, apparently, some other “Gossip Girl” bloggers reside).

Our Serena (the lovely Lively, a longtime resident of Los Angeles, the entertainment capital of the world) is rocking her multi-tiered pale yellow floral chiffon halter gown designed by Ralph Lauren. (A perfect dress for a picnic in the California poppy fields. Hmmm?)

But why so East Coast glum, Serena? What is G up to now? Of course, Blair Waldorf (Leighton Meester) is there, preparing to do battle with G (Michelle Trachtenberg) while wearing a pink Collette Dinnigan frock.

Bad boy Chuck Bass (Ed Westwick) and Dan Humphrey (Penn Badgley) turn up in their formal wear. And you just know that the society wedding of the year will provide Serena the chance to finally pour out her heart and the truth about her past to Dan.

As previously reported, Lydia Hearst guest stars in the episode as Amelia, a stylin’ interior decorator in a pair of amaaaaazing gladiator heels by Siegerson Morrison.

We do wonder if the gossip girls at New York mag have any more daily intel into this wedding scene. After all, it is conveniently located right in their backyard.
